  *This image is copyright of its original author Wiki says: Quote:The dog diverged from a now-extinct population of wolves immediately before the Last Glacial Maximum, when much of Eurasia was a cold, dry mammoth steppe biome.https://www.ancient-origins.net/history/26000-year-old-child-footprints-found-alongside-paw-prints-reveal-oldest-evidence-human-canine-relationhip A recent study suggests that domestication took place from a single population in during a short time somewhere in Eastern Asia from where they migrated, on which another fascinating research was done. But it's likely that ancestors of dogs, weaker & docile outcasts from wild packs, may have been following hunter-gatherers for more than 40k years! There's no reason that feat wasn't replicated elsewhere, penally in smaller scale. This study on genetic diversity of village dogs over the world, found high quite an amount of genetic differences in local strays, actually more than artificially created "breeds" who were basically inbred to highlight certain desired traits. Unfortunately, need for those are mostly gone today & these once functional breeds are being turned into abominations. 
I'm not sure about the scientific terminologies, but I've often wondered about if many of the brown bear subspecies are actually more like different breeds of brown bears. In other words ( my thinking ) less separated genetically. ?

Natural selection > subspecies Artificial selection> breeds Other than that they are the same thing... Nobody bothered to find out the subspecies in stay dogs (there could be scores), otherwise we could compare the differences between it & breeds.

The Carolina dog runs wild right here in my "neck of the woods" very much like a dingo.

I truly had zero idea that such a breed (more like a derivative of GSD) as"King Shephard" exists!
It's a new one that was developed by crossing long-coated european line of German & Shiloh shepherds along with malamutes, back in the '90s. Apparently they don't have the tendency to get crippled with hip dysplasia at older age, due to recessive genes being expressed in purebreds.  *This image is copyright of its original author It's like watching Siberian & Sumatran tigers together.

"King Shepherd" is not a breed; whoever came up with that term and bred that poor dog made an abomination of a true "German Shepherd Dog". There are only 3 recognized GSD's in the SV, FCI, and AKC and they are Long Coat, Short Hair, and Medium Coat and they can be from W.German working lines or show lines, E.German working lines, or American Showline. The "King Shepherd", "Blue Shepherd" are no such thing and many backyard breeders have ruined the original Working Line GSD that Max Von Stephanits worked so hard to create. Breeders should be breeding for their original purpose which is a working line and not breeding for looks as this pushes the GSD far away from its intended purpose plus keeping the horrible health and nerve traits we see with the abomination, American Showline we see today. Hip Dispasia, elbow displasia, spinal stenosis are not a GSD thing. It is common in all canines unfortunately. 
Hi,
The study highlights the long history of human-canine relationships, with evidence suggesting dogs may have been following humans for over 40,000 years. Domestication likely occurred in Eastern Asia, but similar processes could have taken place elsewhere. The genetic diversity found in village dogs worldwide surpasses that of modern dog breeds, which are often inbred for specific traits. To preserve functional diversity, we should focus on maintaining the health of local stray populations rather than overbreeding dogs for appearance, which can lead to health issues. |
